Abstract

An anti-abrasive, flame-resistant, and noise-suppressant laminate suitable for use with underground scraper conveyors or the like comprising two outer layers of ferrous material having an inner layer of styrene butadiene rubber material vulcanized therebetween. The styrene butadiene rubber material has a durometer of the order of 59, a flame spread index of less than 25 according to ASTM-E162 and a thickness of the order of 1/4 inch. One of the outer layers is of abrasive resistant steel and has a thickness of the order of 1/4 inch. The other outer layer is of 1020 steel and has a thickness of 16 gage.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. An anti-abrasive, flame-resistant and noise-suppressant laminate suitable for use with underground scraper conveyors or the like comprising two outer layers of ferrous material having an inner layer of styrene butadiene rubber material vulcanized therebetween, said styrene butadiene rubber material having a durometer of the order of 59 and a flame spread index of less than 25 according to ASTM-E162, one of said outer layers being of abrasive-resistant steel and having a thickness of the order of 1/4 inch. 
     
     
       2. An anti-abrasive, flame-resistant, and noise-suppressant laminate as described in claim 1 wherein said other outer layer has a thickness of the order of 16 gage. 
     
     
       3. An anti-abrasive, flame-resistant, and noise-suppressant laminate as described in claim 2 wherein said other outer layer is of 1020 steel. 
     
     
       4. An anti-abrasive, flame-resistant, and noise-suppressant laminate as described in claim 3 wherein said inner layer has a thickness of the order of 1/4 inch. 
     
     
       5. An anti-abrasive, flame-resistant, and noise-suppressant laminate as described in claim 1 wherein said inner layer had a thickness of the order of 1/4 inch. 
     
     
       6. An anti-abrasive, flame-resistant, and noise-suppressant laminate as described in claim 5 wherein said other outer layer is of 1020 steel. 
     
     
       7. An anti-abrasive, flame-resistant, and noise-suppressant laminate as described in claim 5 wherein said other outer layer has a thickness of the order of 16 gage. 
     
     
       8. An anti-abrasive, flame-resistant, and noise-suppressant laminate as described in claim 1 wherein said other outer layer is of 1020 steel.
